Mopar 5142651AB Power Brake Booster

First remove the master cylinder. On Durango models, also remove the cowl cover, cowl support brace, and windshield wiper arm bracket assembly. Disconnect the vacuum hose from the power brake booster, but do not remove the check valve. Working under the dash, disconnect the power brake push rod from the top of the brake pedal by prying off the clip. Remove the nuts attaching the booster to the firewall. Carefully lift the booster unit away from the firewall and out of the engine compartment, noting the placement of gaskets and spacer blocks.
